Hi, I have been wanting to built this pp kt88 on the above site but I've only built a few se amp including se kt88.
Recently I came across a pair of ppp 6l6 balwdwin amp with massive ptx rated @ 800vct-350ma so I was thinking of building something with it like the pp kt88 on the above site.
So my question is can I run higher b+ like 450v for the kt88 and around 250v for the driver stage? I know kt88 can hadle more than 500v on the plate but I'm not sure about the driver stage because of the interstage trans which I know very litlle about but I'm planing to buy the same interstage trans for the project.

Thanks
Tim
